Tube buffer with 6n3-EV

[McGyver]

What you mean "good tube sound"? Do you want a good sound or "tube sound"?

Yes, good tube sound!!😉

Something like this:

But this isn't a buffer, this is a hybrid integrated chip amp.

That there is at the entrance to the tube buffer with tube 6n11 (see schematics)
I need something similar, but better tube buffer with 6n8s or 6n3p!
thank you

If you want a buffer with gain ~1 you should go for a cathode follower or White follower. But inserting something like that between a source and amplifier is not any good.

 

[Gost22]

Something like that I built with 6n8s or 6n3p, so give a suggestion if you have one.

Is the point of this to have a tube sound and volume control?
- the best way is CDplayer->volume->Buffer->gainclone etc.

As mentioned in other posts here, cathode follower is normally sufficient with modern CD players. It is unlikely you need further gain.

The circuit originally posted reminds me of the Musical Fidelity X-10D tube buffer but half the feedback network appears to be missing....

Maybe some Aikido tube buffer may help!?😕🙄

 

[Gost22]

Hi,
it was just my suggestion, you can perform with your suggestions,...
I appreciate it a lot ...
cheers!!

The Aikido tube buffer design looks sound and it's well documented too shows you basically how to make it into a fully functional preamp too!

tube buffer between CD and Amp

Hello guys

I want to built a tube buffer and connect it to my CD and Amp.
I dont want it inside my CD player.
Dont want to tease the DAC!!
I dont know if i can connect it to the rca output of my CD and the input of my Amp!
I would like some opinions please!
Thank you

Here very nice 6n3 tube buffer which can drive also headphones. First schematic.

Also the backend of the mhzs player works also very good(without the opamp stage)

First schematic is buffer from shanling cd t100 se cd player whitch adds very low harmonics and change very little in sound.

Second schematic is from MHZS cd player with add some more harmonics. A lot of people prefer that sound.

Both schematics you can fit between cd player/Dac and amp.

Made some changes and there you are 😀

I will study it!
It seems okay !
Thank you very much
I apreciate it 🙂

The tube buffer between a source and amp can only spoil the signal quality and never improve. If you are unhappy with sound quality from your Technics CD player, then sell it on ebay, buy cheap Denon based on PCM56 or PCM61 and replace it's analogue stage with passive conversion followed by tube gainstage. The working example you can find on my site: Odtwarzacze CD (must do some scroll down).

that is not true. yes it cannot "improve" specs but it can improve subjective sound through harmonics or twisting of the sound in other ways which can be fun . why else would you buy tubes?

A small improvement could happen , those op amps inside the CD player will see a very high load ( the input impedance of the buffer ) .
But it is much better to eliminate them from signal path , that is not subjective .
